	Change	Effect
1	Base type of 2nd parameter afont_info (pointer) has been changed from PS_FontInfoRec to PS_FontInfoRec_.	Replacement of parameter base type may indicate a change in its semantic meaning.

	Change	Effect
1	Type of 2nd parameter afont_private has been changed from PS_PrivateRec* to PS_Private.	Replacement of parameter data type may indicate a change in its semantic meaning.

	Change	Effect

Problems with Constants (3)

	Change	Effect
1	The value of constant FT_SIZEOF_INT has been changed from 4 to (32 / FT_CHAR_BIT).	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.

	Change	Effect
1	The value of constant FT_SIZEOF_LONG has been changed from 4 to (32 / FT_CHAR_BIT).	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.

	Change	Effect
1	The value of constant FT_VALIDATE_OT has been changed from FT_VALIDATE_BASE \| FT_VALIDATE_GDEF \| FT_VALIDATE_GPOS \| FT_VALIDATE_GSUB \| FT_VALIDATE_JSTF to FT_VALIDATE_BASE \| FT_VALIDATE_GDEF \| FT_VALIDATE_GPOS \| FT_VALIDATE_GSUB \| FT_VALIDATE_JSTF \| FT_VALIDATE_MATH.	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.
